 Helops lucifugus maritimus subsp. n. Resembling luei- 
fugus Woll., of Porto Santo, but more elongate and with 
subparallel sides, elytra more convex, surface more shining. 
The sculpture of the prothorax, with weak punctures on a 
shining surface, shows its relationship to lucifugus rather than 
to H. infernus, which has crowded strong punctures. 9 11°5-12 
mm. long, nearly 6 mm. wide. 3g 9 by about 44 mm. Type 
in British Museum, collected January 1921. Cotype retained 
for U.S. Nat. Museum. 
“ A species of Hadrus was also found on the I. de Nardeste, 
but it must be referred to H. allotus Woll., common on Porto 
Santo. The specimens are narrower than usual, thus varying 
in the same direction as the Helops. On the other islets the 
H. illotus also show incipient differentiation; thus those on 
I. de Cima are conspicuously larger than those on I. de Baixo, 
here varying in a direction parallel with the Scarites just to 
be mentioned. 
 Scarites abbreviatus Dejean, occurs on all the islands, that 
is, on Madeira, Porto Santo and all three Desertas. In 
Madeira I took it near the Pico de Serrado, at an altitude of 
about 3000 ft., Jan. 31. Facing the two ends of Porto Santo, 
and separated from it by narrow channels, are the islands 
called Cima (upper) and Baixo (lower). The latter is consider- 
ably the larger, but appears to be more barren, lacking the 
shrubby Artemisia argentea L’Herit., which abounds on Cima. 
Poor specimens of Nicotiana glauca Graham occur on Baixo; 
the plant was introduced there several years ago by Juan de 
Pico of Porto Santo. S. abbreviatus abounds under stones 
on both these islets, but whereas those on Baixo are about 
19-20 mm. long, somewhat smaller than the Madeira form, 
those on Cima are gigantic. There are, in all, four distinct 
races of S. abbreviatus, which may be separated thus :— 
Large forms. 
“8. abbreviatus cimensis subsp. n. The large form of the 
I. de Cima, not known to Wollaston. It is about 29 mm. long, 
and has the base of the elytra without the numerous granules 
of the Madeira form, but. with a few irregular punctures. 
The mesal expansion of the left mandible has a variable but
